What is Trunnion-mounted?

Trunnion-mounted is a type of ball valve that is widely used in various industries. It is known for its durability, reliability, and excellent performance. In this article, we will explore the features, benefits, and applications of trunnion-mounted ball valves, as well as their advantages over other types of valves.

Features of Trunnion-mounted Ball Valves

Trunnion-mounted ball valves have several distinctive features that set them apart from other types of valves:

1. Design: Trunnion-mounted ball valves have a trunnion, which is a fixed or movable support that holds the ball in place. This design provides additional stability to the valve, allowing it to handle high pressure and high temperature applications.
2. Double block and bleed: Trunnion-mounted ball valves often feature a double block and bleed design, which provides two seals that isolate the valve cavity from the pipeline. This design prevents leakage and ensures the integrity of the fluid flow.
3. Full and reduced bore: Trunnion-mounted ball valves are available in both full and reduced bore designs. The full bore design allows for maximum flow capacity, while the reduced bore design provides a more compact and cost-effective solution.
4. Bi-directional sealing: Trunnion-mounted ball valves offer bi-directional sealing, which means they can effectively seal the flow of fluids in both directions. This feature is essential in applications where the flow direction may change.

Advantages of Trunnion-mounted Ball Valves

Trunnion-mounted ball valves offer several advantages over other types of valves:

1. High pressure and temperature capabilities: Due to their robust design, trunnion-mounted ball valves can withstand high pressure and temperature conditions. This makes them suitable for demanding applications in industries such as oil and gas, petrochemical, and power generation.
2. Excellent sealing performance: The trunnion-mounted ball valve design ensures excellent sealing performance, minimizing the risk of leakage. This is particularly crucial in applications where the fluid being transported is hazardous or valuable.
3. Low torque operation: Trunnion-mounted ball valves require lower torque to operate compared to other types of valves. This not only reduces the wear on the valve components but also allows for easier operation, especially in manual or semi-automated systems.
4. Wide range of materials: Trunnion-mounted ball valves can be manufactured from a variety of materials, including carbon steel, stainless steel, and exotic alloys. This allows for compatibility with different types of fluids and environments.

Applications of Trunnion-mounted Ball Valves

Trunnion-mounted ball valves find applications in various industries and processes:

• Oil and gas: Trunnion-mounted ball valves are widely used in the oil and gas industry for pipeline transportation, refining, and storage applications. They can handle high pressure, high temperature, and corrosive fluids effectively.
• Chemical and petrochemical: Trunnion-mounted ball valves are suitable for handling a wide range of chemicals and petrochemicals. They provide reliable shut-off and control in processes such as distillation, fractionation, and reaction.
• Power generation: Trunnion-mounted ball valves are used in power plants to control the flow of steam, water, and other fluids
